10up Block Patterns

This skill guides you through creating block patterns — reusable arrangements of blocks that users can insert with a single click.

When to Use

• Creating reusable layout components (cards, heroes, CTAs)
• Building content templates for editors
• Setting up starter content for new pages
• Implementing synced patterns for global content
• Using block bindings for dynamic data

Key Concepts

Pattern Type	Description	Use Case
Regular Pattern	Static template, copied on insert	Cards, layouts, sections
Synced Pattern	Global content, updates everywhere	Headers, footers, announcements
Pattern with Bindings	Dynamic data from post meta or other sources	Personalized content

Procedure

Step 1: Create Pattern Directory

Patterns live in the /patterns/ directory of your theme or plugin:

theme-name/
└── patterns/
    ├── card.php
    ├── hero-section.php
    └── call-to-action.php

Step 2: Write Pattern File

patterns/card.php:

<?php
/**
 * Title: Card
 * Slug: theme-name/card
 * Description: A card with image, heading, text, and button
 * Categories: components
 * Keywords: card, box, container, cta
 * Viewport Width: 600
 * Block Types: core/group
 */
?>
<!-- wp:group {"className":"card","style":{"spacing":{"padding":{"top":"var:preset|spacing|30","bottom":"var:preset|spacing|30","left":"var:preset|spacing|30","right":"var:preset|spacing|30"}}}} -->
<div class="wp-block-group card">
    <!-- wp:image {"sizeSlug":"medium","linkDestination":"none"} -->
    <figure class="wp-block-image size-medium">
        <img src="<?php echo esc_url( get_theme_file_uri( 'assets/images/placeholder.jpg' ) ); ?>" alt=""/>
    </figure>
    <!-- /wp:image -->

    <!-- wp:heading {"level":3} -->
    <h3 

Step 3: Pattern Header Fields

Field	Required	Description
Title	Yes	Display name in the inserter
Slug	Yes	Unique identifier (theme-name/pattern-name)
Description	No	Shown in pattern browser tooltip
Categories	No	Comma-separated list of categories
Keywords	No	Search terms for discoverability
Viewport Width	No	Preview width in inserter (default: 1200)
Block Types	No	Blocks this pattern is suggested for
Post Types	No	Limit to specific post types
Template Types	No	Limit to specific template types
Inserter	No	false to hide from inserter

Step 4: Register Custom Categories

add_action( 'init', function() {
    register_block_pattern_category(
        'theme-name-components',
        [
            'label'       => __( 'Components', 'theme-name' ),
            'description' => __( 'Reusable component patterns', 'theme-name' ),
        ]
    );

    register_block_pattern_category(
        'theme-name-pages',
        [
            'label' => __( 'Page Layouts', 'theme-name' ),
        ]
    );
});

Step 5: Dynamic Content in Patterns

Use PHP to inject dynamic values:

<?php
/**
 * Title: Recent Posts
 * Slug: theme-name/recent-posts
 * Categories: posts
 */

$recent_posts = get_posts( [
    'numberposts' => 3,
    'post_status' => 'publish',
] );
?>
<!-- wp:group {"className":"recent-posts"} -->
<div class="wp-block-group recent-posts">
    <?php foreach ( $recent_posts as $post ) : ?>
    <!-- wp:group {"className":"post-card"} -->
    <div class="wp-block-group post-card">
        <!-- wp:heading {"level":3} -->
        <h3><?php echo esc_html( $post->post_title ); ?></h3>
        <!-- /wp:heading -->
        <!-- wp:paragraph -->
        <p><?php echo esc_html( wp_trim_words( $post->post_content, 20 ) ); ?></p>
        <!-- /wp:paragraph -->
    </div>
    <!-- /wp:group -->
    <?php endforeach; 
</div>
<!-- /wp:group -->

Step 6: Create Synced Patterns

Synced patterns (formerly Reusable Blocks) update everywhere when edited.

Register via code:

add_action( 'init', function() {
    // Check if pattern already exists
    $existing = get_posts( [
        'post_type'  => 'wp_block',
        'name'       => 'site-announcement',
        'numberposts' => 1,
    ] );

    if ( empty( $existing ) ) {
        wp_insert_post( [
            'post_title'   => 'Site Announcement',
            'post_name'    => 'site-announcement',
            'post_content' => '<!-- wp:paragraph -->
<p>Important announcement text here.</p>
<!-- /wp:paragraph -->',
            'post_status'  => 'publish',
            'post_type'    => 'wp_block',
        ] );
    }
});

Reference in templates:

<!-- wp:block {"ref":123} /-->

Step 7: Block Bindings API (WordPress 6.5+)

Bind block attributes to dynamic data sources:

<?php
/**
 * Title: Post Hero
 * Slug: theme-name/post-hero
 * Categories: featured
 */
?>
<!-- wp:cover {"useFeaturedImage":true,"dimRatio":50} -->
<div class="wp-block-cover">
    <span class="wp-block-cover__background has-background-dim"></span>
    <div class="wp-block-cover__inner-container">
        <!-- wp:post-title {"level":1} /-->
        <!-- wp:paragraph {"metadata":{"bindings":{"content":{"source":"core/post-meta","args":{"key":"subtitle"}}}}} -->
        <p></p>
        <!-- /wp:paragraph -->
    </div>
</div>
<!-- /wp:cover -->

Register custom binding source:

add_action( 'init', function() {
    register_block_bindings_source(
        'theme-name/site-data',
        [
            'label'              => __( 'Site Data', 'theme-name' ),
            'get_value_callback' => function( $source_args ) {
                if ( 'phone' === $source_args['key'] ) {
                    return get_option( 'theme_phone_number', '' );
                }
                return '';
            },
        ]
    );
});

Common Patterns

Hero Section

<?php
/**
 * Title: Hero Section
 * Slug: theme-name/hero
 * Categories: featured
 * Keywords: hero, banner, header
 * Viewport Width: 1200
 */
?>
<!-- wp:cover {"overlayColor":"contrast","minHeight":500,"align":"full"} -->
<div class="wp-block-cover alignfull" style="min-height:500px">
    <span class="wp-block-cover__background has-contrast-background-color has-background-dim-100 has-background-dim"></span>
    <div class="wp-block-cover__inner-container">
        <!-- wp:heading {"textAlign":"center","level":1} -->
        <h1 class="wp-block-heading has-text-align-center">Welcome   </>
        <!-- /: -->
        <!-- : {:} -->
        <p {:{:,:}} -->
        <div 

Two Column Feature

<?php
/**
 * Title: Two Column Feature
 * Slug: theme-name/two-column-feature
 * Categories: featured
 */
?>
<!-- wp:columns {"align":"wide"} -->
<div class="wp-block-columns alignwide">
    <!-- wp:column -->
    <div class="wp-block-column">
        <!-- wp:image {"sizeSlug":"large"} -->
        <figure class="wp-block-image size-large"><img src="" alt=""/></figure>
        <!-- /wp:image -->
    </div>
    <!-- /wp:column -->
    <!-- wp:column {"verticalAlignment":"center"} -->
    <div class="wp-block-column is-vertically-aligned-center">
        <!-- wp:heading -->
        <h2>Feature Title</h2>
        <!-- /: -->
        <!-- : -->
        <>         .</>
        <!-- /: -->
        <!-- : -->
        < ="--">
            <!-- : -->
            < ="--">< ="--"> </></>
            <!-- /: -->
        </>
        <!-- /: -->
    </>
    <!-- /: -->
</>
<!-- /: -->

Verification

After creating a pattern:

1. Check pattern appears in inserter (+ button → Patterns)
2. Verify it's in the correct category
3. Insert and check block structure is valid
4. Test responsiveness at different viewport widths
5. For synced patterns, verify changes propagate

Failure Modes

Pattern not appearing:

• Check file is in /patterns/ directory
• Verify Title and Slug headers are present
• Check for PHP syntax errors
• Ensure slug is unique

Invalid block markup:

• Block comments must be properly closed
• JSON attributes must be valid
• Check for unescaped characters

Category not showing:

• Register category before patterns load (priority)
• Check category slug matches in pattern

Synced pattern not updating:

• Clear object cache
• Verify post type is wp_block
• Check pattern ref ID is correct

Escalation

Ask the user when:

• Complex dynamic data requirements
• Need pattern variations for different contexts
• Integration with custom post types
• Multi-site pattern sharing
